The post is an essay about how the government has historically misdirected private resources by poorly assessing threats in times of crisis. Why does that make you think that government should be more involved in healthcare?
That doesn't sound very hard to me. Hire people who have the skills necessary, pay them a fair wage (lower probably than they'll make in a corporation, but they'll be working for the people rather than a robber-baron), and let them make vaccines. Aside from the cost, is it really that difficult to do this? We've spent much more on war.
